How the 22219EAKD1 model number is decoded
NTN lists 22219EAKD1 with a 1:12 tapered bore (K) and D1 outer-ring annular oil groove with holes: 95 mm bore, 170 mm OD, 43 mm width, rated 3,000 r/min on grease. Digit by digit the code reads as spherical-roller dimension series plus 95 mm bore; the 43 mm width is the wide ISO 15 section, which is why spherical rollers interchange dimensionally but not in cage or rating detail. The bearing accepts predominantly radial load with a moderate axial share, but is not a pure thrust bearing: sustained axial-only load skids the unloaded row and damages the EA pressed-steel-cage cage. The 37.5 mm section height hosts the spherical roller geometry; shaft and housing fillet radii must clear the chamfer table so the 43 mm-wide ring seats fully on both sides. Fillet radii on shaft and housing must clear the ring chamfers of the 43 mm-wide set; use the NTN shoulder/withdrawal-groove table rather than copying a ball-bearing layout.
Typical equipment & failure modes
Common applications
- large gearbox and marine gear shafts
- wind-turbine gearbox and rotor bearings
- large vibrating screens and mining feeders
- heavy conveyor and bucket-excavator pulleys
Known failure patterns
- lubricant starvation at the centre rib area when the D1/W33 groove is not connected to a relubrication supply
- machined EM cage wear from inadequate oil film at the cage-guiding surfaces
- micro-pitting when the EHL film is thinner than the raceway composite roughness
- brinelling from static overload or a hammer blow during sleeve mounting
- fretting corrosion between adapter sleeve and tapered bore when the drive-up is insufficient
Selection pitfalls — read before you substitute
- Mount the 95 mm ring with induction heat or the sleeve drive-up procedure; at 3900 g cocking damages the spherical raceways, and repositioning after seating is impractical.
- Oil relubrication toward 3,800 r/min needs drain and level design; flooding the 43 mm cavity churns heat through the heavy roller set and cage despite the higher oil speed figure.
- The D1/W33 groove only helps if the housing has a matching grease passage; mounting a D1 22219EAKD1 in a solid block with no port wastes the feature and leaves the centre rows under-lubricated.
- K and K30 are different tapers — K is 1:12 and K30 is 1:30 on the wide series; an adapter sleeve for one will not mount the other 95 mm bearing, and drive-up procedures differ.
- Never substitute 22219EAKD1 by envelope alone: the 417 kN C0 and 33.4 kN Pu are specific to the NTN EA pressed-steel-cage execution, and vibrating duty depends heavily on cage identity.
- The 416/417 kN ratings, 33.4 kN Pu and 3900 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for 22219EAKD1 (EA pressed-steel-cage/D1); another maker's same-envelope part revises internal geometry, so re-verify ratings and cage before substitution on vibrating or rated drives.
Frequently asked questions
What are the dimensions and catalogue data of 22219EAKD1?
22219EAKD1 is an NTN double-row spherical roller bearing to ISO 15: 95 mm bore, 170 mm OD and 43 mm width (3.74 × 6.693 × 1.693 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 416 kN, C0 417 kN, Pu 33.4 kN, grease limiting speed 3,000 r/min, oil 3,800 r/min, mass about 3900 g. It is open, with pressed sheet-steel window cage (EA high-capacity design) and a 1:12 tapered bore.
What is the difference between the K/K30 tapered bore and the cylindrical bore versions?
K denotes a 1:12 tapered bore. 22219EAKD1 mounts on an adapter sleeve (or tapered shaft seat) and is driven up to the specified residual clearance; its cylindrical-bore counterpart in the same envelope and ratings is 22219EAD1.
What do EA and EM mean on NTN spherical roller bearings?
EA is the NTN standard-capacity/high-capacity execution with a pressed sheet-steel window cage; EM is the high-capacity execution with a one-piece machined brass cage. Both use the optimised symmetric-roller design, but cage identity changes mass, speed behaviour and suitability for duties like vibrating screens, so they are separate order numbers. 22219EAKD1 is the EA pressed-steel-cage execution, listed with the ＊ ULTAGE new-generation mark.
What do D1 and W33 mean on 22219EAKD1?
D1 is NTN's outer-ring lubrication feature: an annular groove with oil holes around the outer ring, aligned with a housing grease port so lubricant reaches both roller rows directly. 22219EAKD1 carries D1; W33 is the equivalent industry-spelled annular-groove-and-holes feature seen on other executions.
How much misalignment and axial load can 22219EAKD1 take?
The sphered outer raceway compensates static and dynamic misalignment in the order of 1–2° (verify the exact 2203E figure for the 22200 series); beyond that, load concentrates on one roller row. Load is predominantly radial with a moderate axial share in either direction — 416 kN C / 417 kN C0 — but sustained pure axial load is not recommended because it unloads one row.
